Problems solved by technology

Among them, the bottomless crusher has the advantage of not blocking coal, but it often has the problem that the crushing particle size cannot meet the requirements and the reliability is not high.
However, although the crushers with hole-shaped or strip-shaped sieve plates meet the crushing particle size requirements, coal blocking often occurs, especially sticky coal and wet coal with high water content, which will block the sieve plate and trouble practitioners.

Embodiment 2

[0037] Embodiment two: refer to Figure 7 The difference between this embodiment and the first embodiment is that the cross-sections of the left screen roll 6a and the right screen roll 6b are elliptical. Preferably, the cross-sections of the left screen roll 6a and the right screen roll 6b are congruent ellipse. Since the cross-section of the left screen roller 6a and the right screen roller 6b is circular, the coal sample is subjected to the forces of the left screen roller 6a and the right screen roller 6b, which are symmetrical to each other, so there may still be a small degree of blockage . Therefore, the cross section of the left sieve roller 6a and the right sieve roller 6b can also be adopted to be an elliptical form. At this time, the coal sample is subjected to the asymmetrical force of the left sieve roller 6a and the right sieve roller 6b, so it can be Unloading smoothly.

[0038] And, preferably, the acute angle formed by the long axis of the ellipse of the le...

Embodiment 3

[0039] Embodiment three: refer to Figure 8 The difference between this embodiment and the first embodiment is that two pairs of sieve rollers 6 that can sieve particles are rotated at the discharge port 4, thereby further speeding up the sieving efficiency.

Abstract

The invention discloses a movable mesh sieve roller breaking machine. The movable mesh sieve roller breaking machine comprises a rack, a feeding opening, a breaking cavity, a hammer and a dischargingopening; at least one pair of sieve rollers capable of screening particles are arranged on the discharging opening rotatably, the breaking machine can break the coal samples through the feeding opening, the breaking cavity, the hammer and the discharging opening, the sieve rollers can carry out real dynamic screening on the coal samples, it is ensured that the breaking granularity of the coal samples can meet the requirement, coal blockage is prevented, the coal sample is further broken, the manner that feeding is carried out over a cylinder formed by a breaking hammer traditionally is brokenthrough the breaking machine, feeding at the shaft end is particularly achieved, the coal can be subject to comprehensive 360-degree full-circumference full-cavity dead-corner-free no-residual breaking. According to the field, sieve structures of a sieve net and the like take meshes as the measuring units, sieve plate structures of a traditional hole-shaped and strip-shaped sieve plate breaking machine are static and therefore are called as fixed meshes, compared with a traditional breaking machine, the movable sieve rollers can be called as movable meshes, and the breaking machine is called as the movable mesh sieve roller breaking machine.

Description

technical field [0001] The invention relates to the technical field of coal sample crushing, in particular to a live mesh roller crushing structure for crushing coal samples. Background technique [0002] At present, the crushers on the market are mainly crushers without sieve bottoms or hole-shaped and strip-shaped sieve plate crushers. Among them, the crusher without sieve bottom has the advantage of not blocking coal, but the crushing particle size often fails to meet the requirements and the reliability is not high. However, although the crushers with hole-shaped or strip-shaped sieve plates meet the requirements of crushing particle size, coal blocking often occurs, especially sticky coal and wet coal with high water content, which will block the sieve plate and trouble practitioners. [0003] At the same time, the hammer head of the crusher rotates in the vertical direction to form a cylinder. The feed inlet of the traditional crusher is located directly above the ro...
